Electrical Engineering
Electrical engineering is the thread connecting all domains in this vault. These notes span the full stack: from the physics of electrons to the operation of large-scale power grids to the control algorithms that keep them stable.
Subdisciplines
Power Systems Engineering
Generation, transmission, and delivery of bulk electric power. Load flow, fault analysis, protection, stability, and grid operations.
Distribution Power Systems
The last mile of the grid — the systems that deliver power to homes, businesses, and distributed resources. Planning, protection, automation, and modernization.
Renewable Energy & Distributed Energy Resources
Solar, wind, storage, microgrids, and the integration of distributed generation into the grid. Inverter-based resources and grid services.
Power Electronics
Converters, inverters, rectifiers, and drives. The interface between electrical machines, the grid, and distributed energy resources.
Control Systems
Feedback, stability, PID controllers, state-space methods, and modern control. The theory behind automatic regulation of any dynamic system.
Communications & Networking
Communication protocols, SCADA, IEC 61850, DNP3, fiber and wireless for grid infrastructure, and cybersecurity interfaces.
